        IPAddress[] addr = ipentry.AddressList;// Resolving IP Addresses
        for (int i = 0; i < addr.Length; i++)
        {
            try
            {
                ipLabel.Text=  Convert.ToString(addr[i]) + "\r\n";

string strHostName = "";
 strHostName = System.Net.Dns.GetHostName();
 IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName);
 IPAddress[] addr = ipEntry.AddressList;
 ipLabel.Text = addr[addr.Length - 2].ToString();
